Abstract

Biomass based energy system play an important role for developing countries like India which is rich in biomass. In this work, biomass is utilized in decentralized way for multiple utility generation through polygeneration. However, for the maximum utilization of biomass, proper design of energy system is necessary. For this purpose, exergy analysis shows better insight about the scope of the possible improvement. Results indicate the critical components and processes of the polygeneration from the viewpoint of exergy. Most of the exergy losses and destructions occur in gasification, ethanol production and combustion processes. Thermodynamic parameters for all state points of the polygeneration are reported in this paper.
